Direct replacement for ThinkPad P40 Yoga

This Dr. Battery MPL10305P-18 is a new lithium-polymer pack built to match the original 11.4 V 4540 mAh 53 Wh specification. It fits the ThinkPad P40 Yoga models listed in the compatibility table including 20GQ series units. Owners of those machines can restore factory runtime without adapting cables or firmware.

Drop-in fit frees the original charger

The battery uses the stock connector and form factor so it slides into the existing bay and locks with the original latch. No extra brackets, wiring harnesses or BIOS updates are required. The integrated smart control chip handles charge negotiation with the laptop's power controller, leaving the AC adapter and motherboard circuitry unchanged.

Low heat and silent operation

Lithium-polymer chemistry runs cool during typical workloads and the pack has no moving parts so it adds zero acoustic noise. Built-in protection circuits guard against short circuit, overheat and overload conditions while the smart chip optimises charge current for lower consumption and longer discharge cycles.

Questions about this item

How long will the 53 Wh capacity last before the smart control chip triggers overload protection during continuous use?

The built-in smart control chip manages charging and discharging to extend runtime, and overload protection activates only if current exceeds safe limits, not after a fixed time.

Does the lithium-polymer cell generate noticeable heat or fan noise when the laptop runs all day on this 11.4 V battery?

The battery itself has no moving parts and produces minimal heat; any fan noise comes from the laptop's own cooling system, not from the battery pack.

Must the original Lenovo ThinkPad Yoga 460 or P40 Yoga chassis already be in working order for this MPL10305P-18 pack to function?

Yes, the battery is a direct replacement for the listed ThinkPad models and requires a compatible laptop with a functional battery connector and charging circuit.
